The right number of CCTV cameras is not a fixed figure. It depends on how many ways someone can get into your property and which areas you want a clear record of. Too few cameras leave blind spots; too many waste money on overlapping views. Here is how we plan it during a site survey.
Start with the entry points
Walk around your property and list every way a person could enter: the main gate, the main door, a side or back door, a service entrance, the terrace door and any low boundary wall. Each entry point should be covered by at least one camera that can see a face, not just a figure.
Typical camera positions
| Area | Why it matters | Camera tip |
|---|---|---|
| Main gate | Every visitor and vehicle passes here | Mount at a height that captures faces and number plates |
| Main door | Deliveries and visitors at close range | A wide view, or pair with a video door phone |
| Car parking | Vehicles and two-wheelers | Colour-at-night cameras help in dark parking areas |
| Side and back passages | Common route for intruders | Cover the full length of the passage |
| Terrace / staircase | Access from neighbouring buildings | One camera at the terrace door |
| Indoors (optional) | Staff, elderly parents, children | Living area or hall only; respect privacy |
Rough guide by property type
- Apartment: usually one camera at the main door, or a video door phone instead.
- Independent house: usually gate, main door, parking and one or two side passages.
- Villa with a large plot: add cameras along the boundary wall, the garden and the terrace.
These are starting points. Corner plots, multiple gates and long boundary walls change the count, which is why we always confirm on site.
How much recording storage do you need?
Storage depends on the number of cameras, their resolution and how many days of footage you want to keep. Decide the number of days first, then size the hard disk to match. Most homes keep a few weeks of recording; businesses often need longer. Your installer should tell you exactly how many days your hard disk will hold.
IP or HD analogue cameras?
IP cameras give sharper images and smarter features such as person detection. HD analogue cameras are cost-effective for smaller set-ups. Both can be viewed on your phone. The right choice depends on your property and budget.
Do not forget maintenance
Cameras collect dust, angles shift and hard disks fail quietly. Many owners find out only when they need footage and it is not there. A CCTV AMC with scheduled checks keeps every camera recording.
